I just looked into it, no one seems to know exactly what it means, other than a symbol of recognition that they are a fellow illuminati club member. But I believe there was a deeper meaning to McConnell which he immediately acknowledged. One of the twitter posts with this video, had a subsequent post that showed McConnell had been beaten up. He came to work with bruises around his lips and big bruises on his right hand. Maybe he was tortured or roughed up to remind him who is boss or something like that. When asked about all his bruises apparently McConnell got angry, and his staff were zip locked mouthed. McConnell has definitely appeared to flip to the Deep state lately. Of course his wife is CCP. But McConnell pushed through a lot of conservative Judges for Trump in these past 4 years, along with other nominations. When people are controlled by blackmail, they do irregular things. This election was definitely high stakes for everyone around the world. A lot of SCARED/Blackmailed people on Capitol Hill. If they don't do as they are told, the Deep State could take out one of their children, things like that.
